Resize PDF Pages
About this tool
Resize PDF Pages — One Page Size for the Whole File
Give every page of a PDF the same size — A4, Letter, A5, Legal, a custom size or the size most pages already have. Everything runs locally in your browser — no upload, no sign-up, no watermark and no file size limit.
Scale to Fit or Centre
Scale each page up or down until it fills the new size, or keep it at 100 % and centre it with a white border. Portrait and landscape follow each page, so a landscape table stays landscape.
Text, Links and Bookmarks Keep Working
Pages are not turned into pictures or copied into a new file. Each page gets a new size and its content a transform, and links, comments, form fields and bookmark targets move with it, so text stays selectable and every link still lands in the right place.
Binding Margin in the Same Tool
Switch to Binding margin to add a few millimetres for a hole punch or binding, mirrored for double-sided printing, by shrinking the content or widening the page.
How to use it
- Drop the PDF with mixed page sizes.
- Pick A4, Letter, A5, Legal, a custom size in millimetres, or the most common size in the file.
- Choose Scale to fit, or Centre with a white border to keep everything at 100 %.
- Click Resize pages and download the PDF.
Frequently asked questions
Are my PDFs uploaded to a server?
No. Toolula processes the document inside your browser tab with pdf-lib and WebAssembly, so the file never leaves your device.
Will the text still be selectable and searchable?
Yes. The original page content is kept and only placed differently, so text, fonts and vector drawings stay exactly as sharp and selectable as before.
What happens to pages that are already the right size?
They are left untouched. The result says how many pages were changed.
Does it keep rotated pages?
Yes. A page's rotation stays as it is, and its orientation on screen decides whether it becomes portrait or landscape.
What is the most common size?
The page size that most pages of the file already have, counting portrait and landscape together. It is the quickest way to bring a few odd pages — a scanned receipt, a Letter page in an A4 report — in line.
Is it really free?
Yes. You can use every Toolula PDF tool for free, without an account. The free plan has fair-use limits; Toolula Pro, an optional plan, raises them and adds advanced features.
